Components are used to restrict results to a specific area. A filter consists of one or more of: route, locality, administrativeArea, postalCode, country. Only the results that match all the filters will be returned. Filter values support the same methods of spelling correction and partial matching as other geocoding requests. Optional.

LatLng (or LatLngLiteral) for which to search. The geocoder performs a reverse geocode. See Reverse Geocoding for more information. One, and only one, of address, location and placeId must be supplied.

The place ID associated with the location. Place IDs uniquely identify a place in the Google Places database and on Google Maps. Learn more about place IDs in the Places API developer guide. The geocoder performs a reverse geocode. See Reverse Geocoding for more information. One, and only one, of address, location and placeId must be supplied.

A single geocoder result retrieved from the geocode server. A geocode request may return multiple result objects. Note that though this result is "JSON-like," it is not strictly JSON, as it indirectly includes a LatLng object.

An array of strings denoting all the localities contained in a postal code. This is only present when the result is a postal code that contains multiple localities. This array can contain up to 10 localities.

The returned result reflects an approximation (usually on a road) interpolated between two precise points (such as intersections). Interpolated results are generally returned when rooftop geocodes are unavailable for a street address.
